Draining the Engine
This procedure covers draining the raw (sea) water
from the heat exchanger and seawater pump. This is
usually done to prevent damage to these parts during
freezing temperatures.
Before starting this process, ensure that there is an
indexing mark on the heat exchanger and a
corresponding mark on the end cap at B. If there are
no marks, use a white paint marker to create the
indexing marks.
NOTICE! This indexing mark is required to ensure that
the raw water inlet C is in the correct position when the
end cap is reinstalled.
1 Loosen clamps on raw water pump hoses D and E.
Lower ends of the hoses below the level of the oil
cooler and the bottom of the heat exchanger. Allow
water to completely drain.
2 Loosen 9/16” nut A on the stud holding the end cap
on the bottom of the heat exchanger. Do not
remove the nut from the stud.
3 Make sure the cap completely separates from the
heat exchanger.
NOTICE! Risk of freeze damage to heat exchanger.
The raw water portion of the heat exchanger has
multiple compartments, to insure that all
compartments drain, the cap must completely
separate from the gasket and housing.
4 Once the end cap has come loose, water will begin
to drain from the heat exchanger. Allow all water to
drain.
5 Reinstall the end cap, using the indexing marks to
properly align the cap. Tighten nut until cap and
gasket are sealed to the bottom of the heat
exchanger. Do not over tighten nut, maximum
torque is 10–11 ft. lb. (14–15 Nm).
6 Reinstall the hoses D and E and tighten clamps.
